I have just finished the final touches on my first DIY build, but I have one problem: The CPU or mobo didn't come with a heatsink or CPU fan of any kind. I thought intel gave them out w/ the processors but mine didn't have a thing and now I'm stuck with a computer lacking any sort of CPU cooling. I'd like to avoid ordering it online-it would be nice to head over to a store and pick it up right now. I have an E6600, an ECS P965A-T mobo, and a coolermaster centurion. The price limit is about $15. Thanks
Don't forget that you still need thermal compound; all of the reccomendations here don't come with grease. This Masscool hsf is the cheapest one on newegg that includes thermal compound at $11. It doesn't have a 4 pin connector, but you don't really need 4 pins. If you just plug it in it will run at full speed all of the time (and still be 10db quieter than the stock intel fan) or you can run freeware like speedfan in windows to control fan speed.
